Thetford is a market town and civil parish in the Breckland district of Norfolk, England. It is on the A11 road between Norwich and London, just south of Thetford Forest. The civil parish, covering an area of 29.55 km² (11.41 sq mi), has a population of 21,588.

Thetford is traditionally thought of as the royal residence of Boudica^{[citation needed]} Queen of the Iceni. The Iceni were a Celtic tribe living in Norfolk and parts of Cambridgeshire. Archaeological evidence suggests that Thetford was an important tribal centre during the late Iron Age and early Roman period. A ceremonial 'grove' was uncovered there during excavations. In 1979, a hoard of Romano-British metalwork, known as the Thetford treasure was located just outside of Thetford. Dating from the mid-4th Century AD, this hoard is a collection of thirty three inscribed spoons, twenty gold finger rings, four pendants, several necklaces and a 2" gold buckle depicting a dancing satyr. They are currently on display and under curation at the British Museum.

Ian Grant (born 15 December 1930) is a British physicist and a Fellow of the Royal Society.

He was a founding member of University of Oxford's Department of Theoretical Chemistry in 1972. He was Professor of Mathematical Physics, University of Oxford, 1992-98, now Emeritus Professor. With a solid background in numerical analysis, Grant and co-workers pioneered many useful and versatile algorithms and methods ranging from "GRASP" (General Purpose Relativistic Atomic Structure Program) for relativistic atomic structure calculations based on 4-component methods to code generation tools for calculating molecular integrals.
